The temperature is a sign of the average molecular function, which determines whether a system with other systems in thermal equilibrium physical quantities, and its basic features is that all mutual thermal equilibrium have the same temperature. When the temperature is low, the speed of the molecules, atoms vibration is very small and can not get rid of the molecules, atoms become smaller, the distance between molecules larger, the substance is liquid. With the temperature rising, the molecular motion is very intense, the distance between molecules is larger, at this time material for the gas. The whole world is so wonderful is because of these different molecules, atoms in different temperature changes from

什么是宇宙温度
In which the entire universe, the temperature of the ubiquitous presence. Both on Earth and the moon, but also whether it is in the red hot sun or cold on Pluto, all these are all different due to the spatial location of the existence of the temperature difference. For example, the sun's surface temperature is 6000 ° C, while in the solar system far from the sun, Pluto's surface temperature is only -240 ° C. In another example, the legendary Altair and Vega, in the night sky, they are just the flashing highlights, how can people suddenly think Altair's maximum surface temperature as high as 8000 ° C, the maximum surface temperature of the Vega as high as 10000 ° C turns out to be a Star "in love".
